| 13:57 | Merge enhancements from trunk. check-in: 9e10d88b user: drh tags: apple-osx | |
| 13:51 | On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. check-in: 90cf32cd user: drh tags: trunk | |
| 10:37 | In the CLI, fix a file descriptor leak following OOM and a missing va_end() call. check-in: ec36d15a user: drh tags: trunk | |

|
2018-10-04
| ||
| 18:17 | The 0x8000 optimization flag associated with SQLITE_TESTCTRL_OPTIMIZATIONS causes a large penalty (200) to be added to all sorting costs, which encourages the query planner avoid using the sorter. This flag can be used in experiments to help come up with a more accurate estimate of the true cost of sorting. Leaf check-in: 857a1b01 user: drh tags: query-planner-debug | |
|
2018-10-03
| ||

| 19:36 | Fix comments and refactor some names associated with shared-memory locking in the Unix VFS. No logical changes. check-in: 3e9f1635 user: drh tags: trunk | |
|
2018-10-01
| ||
| 21:41 | Add the "PRAGMA table_xinfo" command that works like table_info but also shows hidden columns in virtual tables and adds the "hidden" boolean column. check-in: defa0515 user: drh tags: trunk | |
| 21:36 | Test case for PRAGMA table_xinfo. Closed-Leaf check-in: 7694b9bc user: drh tags: pragma-table-vinfo | |

|
2018-09-29
| ||
| 19:38 | Add the PRAGMA table_vinfo command (with an extra "v" before "info") that works like PRAGMA table_info (without the "v") except that it also shows hidden columns on virtual tables. check-in: 8bcd1a59 user: drh tags: pragma-table-vinfo | |
|
2018-09-28

| 18:02 | Further improvements to the ".help" command in the CLI. check-in: edc3d18e user: drh tags: trunk | |
| 16:53 | Begin revamping the ".help" command in the command-line shell so that it can accept an argument and will do a search for commands that match that argument. check-in: 209afb8d user: drh tags: trunk | |
| 16:05 | Tweak spellfix.c so that if SQLITE_SPELLFIX_5BYTE_MAPPINGS is defined at compile time the Transliteration structure has space for 5 byte (instead of 4 byte) mappings. check-in: cbaf5b6c user: dan tags: trunk | |

| 14:10 | Allow a writable virtual table to have a schema with an INTEGER PRIMARY KEY and WITHOUT ROWID. This fixes ticket [f25d5ceebe1d710ff61a571e395356869d8272ef]. Test case in TH3. check-in: 5a38d928 user: drh tags: trunk | |
| 12:37 | Use compile-time options SQLITE_QUERY_PLANNER_LIMIT and SQLITE_QUERY_PLANNER_LIMIT_INCR to control the value for WhereLoopBuilder.iPlanLimit, rather than embedding magic numbers in the code. check-in: 903e5018 user: drh tags: trunk | |
| 10:47 | Increase the initial value of WhereLoopBuilder.iPlanLimit to 20K. Issue a warning if the iPlanLimit reaches zero. check-in: 3dd35f51 user: drh tags: trunk | |
|
2018-09-23
| ||

2018-09-20
| ||
| 20:43 | Minor code simplification. check-in: 22ae8a52 user: drh tags: trunk | |
| 20:15 | Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. check-in: 7edd26ed user: drh tags: trunk | |
| 19:02 | Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. check-in: ad130bb8 user: drh tags: trunk | |
| 17:21 | By default, make all "ALTER TABLE RENAME" statements executed within a virtual table xRename() method exhibit the legacy behaviour. Closed-Leaf check-in: 71947337 user: dan tags: legacy-alter-table | |
| 08:28 | Add a PRAGMA that restores the legacy ALTER TABLE RENAME TO behaviour. check-in: 5acad2e9 user: dan tags: legacy-alter-table | |

| 17:00 | Enhance tester.tcl so that when "--malloctrace=1" is specified, the test generates self-contained Tcl scripts that present GUIs instead of *.sql files that require a separate program to interpret. check-in: de2e3cbd user: dan tags: trunk | |
| 16:06 | Minor improvements to the permutations.test script. Most notably, a command like "permutations.test alter%" now runs all test scripts with names that match the LIKE pattern "alter%". Or, say, "permutations wal alter%" to run all alter% tests in wal mode. check-in: 3e1a2f66 user: dan tags: trunk | |

| 15:19 | Disable the ORDER BY LIMIT optimization in queries using window functions. This fixes a problem that was introduced by check-in [206720129ed2fa8875a286] which attempted to fix ticket [9936b2fa443fec03ff25f9]. This changes is a fix for the follow-in tocket [510cde277783b5fb5de628]. check-in: c6c9585f user: drh tags: trunk | |
| 14:13 | Fix a false-positive in the post-ALTER-TABLE schema verification logic that prevents ALTER TABLE from working if the table being altered has a trigger that references any column of a virtual table. Ticket [b41031ea2b537237]. check-in: 84105ea4 user: drh tags: trunk | |
| 13:55 | Restore an assert() that was present on trunk. Closed-Leaf check-in: a7b572ca user: drh tags: tkt-b41031ea | |

| 15:01 | Improved presentation on the new code that prevents unnecessary writes to expressions on indexes during an UPDATE when the expression does not reference any of the columns that are changing. check-in: c9f04529 user: drh tags: trunk | |
|
2018-09-15
